"Dark Star" is a song released as a single by the Grateful Dead on Warner Bros. records in 1968. It was written by lyricist Robert Hunter and composed by lead guitarist Jerry Garcia; however, compositional credit is sometimes extended to include Phil Lesh, Bill Kreutzmann, Mickey Hart, Ron "Pigpen" McKernan, and Bob Weir. "Dark Star" was an early Grateful Dead classic and became one of their most loved and anticipated numbers, often with the group using it as a vehicle for musical improvisation sessions that extended beyond the original structure of the song. The song is included in The Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll list and was ranked at number 57 on Rolling Stone's 100 Greatest Guitar Songs of All Time. "Dark Star" was often the basis for jamming during the Dead's live shows, allowing the band to employ techniques typical of improvisational jazz.
